PUMP FOR MEASURING, MIXING, BLENDING, 0R DILUTING LIQUIDS.

SPECIFICATION forming part of Letters Patent N 0. 712,164, dated October28, 1902.

Application filed January 24,1902. Serial No. 91 ,076. N model) To allwhom it may concern:

Be it known that I, RALPH G. WHITLOCK, of the city of Los Angeles, inthe county of Los Angeles and State of California, have invented acertain new or Improved Pump for Measuring, Mixing, Blending, orDiluting Liquids, which may be used for other pumping operations, ofwhich the following is a full, clear, and exact description orspecification, reference being had to the annexed sheets of drawings andto the letters marked thereon. I Y

My said invention, which relates to pumps especially applicable formeasuring, mixing, blending, or diluting liquors, may also be used forpumping liquors from any container or vessel into any other container orvessel.

The essential feature of my said invention consists in the arrangementof the ports in a plug or valve casing forming part of my pumpingmechanism and in the ports in the interchangeable rotatable hollow plugsor valves contained and operated within said plug or valve casing,whereby it results that that opening in any of the plugs or valveswhereby liquid passes into or out of the pump barrel or cylinder isalways open, so that there is free and unobstructed passage at all timesbetween the pump barrel or cylinder and the interior hollow space of theplugs or valves, and this irrespective of whether the other ports in theplugs or valves are open to either one or more of the ports in. the plugor valve casing through which liquid is drawn into the pump or whetherthese ports are shut to the ports in the plug or valve casing and opento the discharge-port therein. The ports in the casing are or may be ofsuch number as is necessary to admit into a pump the maximum number ofliquids which are to be measured, mixed, blended, or diluted, and,

the number of ports in a plug or valve is such as to admit either suchmaximum number of liquids or any desired less number of liquids (thanthe number of ports in the plug or valve casing) to be measured, mixed,blended, or diluted in order to produce any definite proportion ofmeasuring, mixing, blending, or diluting of said liquids, so that whilethe plug or valve casing is adapted for its ports being connected bymeans of flexible pipes, such as rubber hose-pipes, or by pipes of anyother suitable kind, with any desired number of casks or other vesselscontaining liquids which are to be measured,

mixed, blended, or diluted, yet the plugs or valves which operate inthis plug or valve casing are constructed with ports which are so placedin the plugs or valves that these ports in the plugs or valves may be ofsuch number that they may open to the maximum number ofv ports in theplug-casing or to any less number than the maximum number of ports inthe plug-casing. Thus it follows that when my new or improved pump isused for measuring, mixing, blending, or diluting a very varied numberof liquors-that is to say, in different numbers of the liquors to bemeasured, mixed, blended, or dilutedthen it is necessary for the pumpingapparatus to be provided witha sufiicient number of such structedconnection between the pump and the interior hollow or space of the plugor valve whereinto all the ports in the plug or valve open, so thatliquid passing through the several ports in the plug or valve from thecasks or barrels through which such liquids are drawn can flowfreelyinto the pump barrel or cylinder during the pumping stroke of thepiston or plunger therein, and the moment that a valve-plug is turned ormoved in the casing, so as to close the ports leading to the casks orbarrels and to open the discharge-port, then this port in the hollow ofany of the plugs or valves as freely and unobstructedly connects theinterior of the pump barrel or cylinder with the discharge-port ofthepump.

It is to be understood that the sizes of the ports in the plugconnecting with the casks or barrels from which liquids to be measured,mixed, blended, or diluted are such as may be required to allow anydesired proportion of each liquid to. be drawn into the pump.

In using the pump constituting my invention for measuring, mixing,blending, or diluting corrosive liquids the pump barrel 0r cylinder, thepiston or plunger, and the plugcasing, with the several ports formingpart thereof, are by preference made of aluminium, as being anon-corrosive or but very slightly corrosive metal and in order that theplug or valve may operate easily and without cutting the receptacle inthe plugcasing wherein it operates.

On the annexed sheets of drawings, Figure 1 is a side elevation of mynew or improved pump for measuring, mixing, blending, or dilutingliquors. Fig. 2 is an end elevation of my said pump looked at in thedirection of the arrow marked X on the right-hand side of Fig. 1. Fig. 3is a section of the pump barrel or cylinder with the piston andpistonrod therein. Fig. 4 is an edge elevation of the cable-quadrant foroperating the piston or plunger of the pump, as hereinafter described.Fig. 5 is a horizontal section of the pump-barrel on the line a Ct,Figs. 1, 2,and 3, and showing the plug or valve casing, a tapered plugor valve, and the nozzles connecting with the ports in the tapered plug.Fig. 6 is a horizontal section through the cylinder and through thetapered plug or valve casing, through the tapered plug or valve itself,and through three of the nozzles for connecting barrels, casks, or otherreceptacles containing liquid with the pump, the tapered plug or valvein this case having its ports arranged for connecting with three of theports in the casing, to which the nozzles thereof are connected byflexible rubber hose or equivalent pipes. Fig. 7 is a vertical sectionthrough the casing, showing the connection of the ports in the taperedplug or valve with two inlet ports and nozzles, also the port connectingthe whole interior of the tapered plug with the bottom of the pumpbarrel or cylinder and the discharge-port. Fig. 8 is a horizontalsection of part of the pump-barrel and having the tapered plug or valveconstructed with but one port therein for the purpose of drawing orpumping one liquid at a time from any barrel or receptacle and fordischarging it measured into any other barrel or receptacle. Fig. 9 is asimilar horizontal section to Fig. 8, but shown as containing a taperedplug or valve with ports therein for connecting with three of the portsin the casing for measuring and mixing three liquids ata time. Fig. 10is an elevation, partly in section, for connecting the pump with thecasks or receptacles from which liquids are pumped for being measured,blended, or diluted.

As shown by Figs. 1, 2, and 3 more especially, my new or improved pumpconsists of a cylinder marked A, whereinto is fitted a piston B, moreespecially shown in section at Fig. 3. This piston B is screwed onto thelower end of the piston-rod O in the manner also shown at Fig. 3-that isto say, the piston-rod C does not project through the piston B, butinstead thereof the lower end and the entire piston-rod G are maintainedalways out of contact with the liquid or liquids passing through thepump barrel or cylinder A in order to prevent any corrosive liquid orliquids which may be passed through the pump-barrel A from coming intocontact with any part of the piston-rod C. The pump barrel or cylinder Aand the piston or plunger B, besides all the other parts with which theliquid or liquids passed through the pump come into contact, areconstructed of aluminium or other non-corrosive metal or material, sothat no chemical action whatever can take place between the material ofwhich the interior parts of the pump are constructed and the liquid orliquids passed through the pump, from which arrangement it follows thatthe liquid or liquids is or are discharged from the pump either measuredin their normal conditionthat is to say, when not mixed, blended, ordiluted-or in their chemically-pure condition when measured, mixed,blended, or diluted. The piston B of the pump is so operated thatitsaction completely fills and completely discharges the whole of theliquid taken into the pump-barrel A at every stroke thereof, and as thepump-barrel A is of such dimension as to contain an exact measuredquantity of liquid-say, for example, a gallon or less or more than agallon-it follows that my new or improved pump is also a measuringdevice for the quantity of liquid passed through it, which is alwaysascertained by counting the number of strokes of the pump in onedirection only. For example, if the upward stroke of my new or improvedpump causes one gallon of liquid to be taken into the pump barrel orcylinder A, then any nu mber of such strokes will cause that number ofgallons to be passed into the pump barrel or cylinder and discharged bythe opposite strokes of the piston into any receptacle whereinto thesame may be delivered.

The upper part or cover D of the pump-barrel or cylinder A may beconstructed of cast iron or other sufficiently strong material, and fromone side thereof there projects the inclined arm E, upon the upper outerend of which there is pivotally carried the cablequadrant F F, movableupon the pivot F. As shown at Figs. 1, 2, and 4, two short lengths ofcable or rope (marked G and H, respecively) connect this cable-quadrantF F with the piston-rod O in the manner now to be described.

The lower end of the cable G is fastened into the clench I, Figs. 1 and2, and the upper end of the cable Gis fastened to the vertical rear partby the clench adjustable nut and eyebolt J and K, Fig. 1, the eyebolt Kpassing through the hole in the lug L,'as shown in this figure. Thecable H is fastened to the clench M at the upper part of the piston-rodO C, as shown at Figs. 1 and 2, and to the lower part of the cablequadrant F F by means of a nut and eyebolt N and 0, respectively, theeyebolt O passing through the lug P, as shown. By means of thisarrangement and connections of the cable-quadrant F, the cables G and H,and the piston-rod G as the cable-quadrant F F is moved pivotally uponits pivot F by the operator either pressing downward or lifting upwardthe handle Q, so the piston-rod G and its piston B B are reciprocatedcompletely within the pump barrel or cylinder A A through each upward ordownward stroke of the piston-rod O and its piston D.

At one side of the lower part of the pump barrel or cylinder A the plugor valve casing R projects, as shownat Figs. 1 and-2, and this casing Ris by preference cast in one piece with the lower part of the pumpbarrel or cylinder A. The construction of this casing is obvious fromthe drawings, wherein four nozzles S S S S are shown projecting from theouter part of the casing R in the positions indicated on the drawings,and each of these nozzles S S S S is tapered from its rear toward theouter end thereof in order to admit of a piece of rubber hose orequivalent flexible pipe to be pushed tight on the nozzles S S S S,respectively, while the other or outer end of such india-rubber hose orflexible pipe is connected to the nozzle S of the tapered connector S,which is driven into a hole in each barrel, cask, or other receptaclefrom which liquid is to be drawn into the pump. The barrels or otherreceptacles from which liquid is pumped when using my invention mustalways be placed upon such a level relatively with the pump that thepipes connecting the nozzles S S S S thereto never have any air in them,which condition is insured by placing the pump on a lower level than thebarrels or receptacles, so that a column of liquid always presses downinto the pump apparatus. The tapered plug or valve (marked T in thedrawings) is formed with a square projection at its upper end, uponwhich the operating-handle U, Figs. 1, 2, 5, and 6, fits. Thisoperating-handle is provided at its under side with a strong yieldingcatch device, (marked V,) the inner end of which engages with either ofthe holes V V V, out into the periphery of the upper part of the casingR of the taper plug, as more particularly shown at Fig. 5, and the plugor valve T is maintained in its operative condition in the casing-R bymeans of the pulling action of the spiral spring W, Figs. 1, 2, and 7,which, acting downward upon the washer W, held on the bottom of thetapered plug T by the split pin Y, always maintains the tapered plug orvalve '1 held downward into its operative position within the casing R.

According to the numbers expressing any part of admixture, blending, ordilution of a liquid, so the ports for admitting said liquids from pipesconnected to the nozzles S S S S are varied in their number andpositions in the tapered plug or valve T, and in order to illustratesuch variations I have shown in Figs. 6 and 7 the arrangements of theports in the tapered plug or valve T to enable any two liquids to beadmixed in the proportion The nozzles S and S are connected to awater-tank or other vessel containing the water to be used formeasuring, mixing, blending, or diluting vinegar, and the nozzle S isthat through which the vinegar is ad mitted into the apparatusconstituting my invention in the position of the tapered plug or valveT. (Shown at Figs. 6 and 7.) The ports T therein, which connect with thewater-nozzles S and S, and the port T, which connects with thevinegar-port S, are both shown as shut off from the nozzles S", S, andS, respectively, which position of the tapered plug or valve T and itsports T and T correspond with the pump, being in the condition of havingthe pump barrel or cylinder filled with water and vinegar measured,mixed, blended, or diluted in the proportions now last described, andwhen the tapered plug or valve T is in the position shown at Figs. 6 and7 then the liquid in the pump barrel or cylinder A is in direct orunobstructed communication with the discharge orifice or nozzle U. Byreason of the plug or valve T being in the'position when its large port(marked T) is open to the interior of the pump barrel or cylinder A,through the permanent opening therein, (marked U,) and in which positionthe port T in the tapered plug T is also open to the discharge-nozzle U,it follows that on mak-. ing the downward stroke of the piston-rod G andpiston B B all the liquid contained within the pump barrel or cylinder Ais discharged through the port U, through the port T, through the portT, and into the dischargenozzle U, and when the discharge has thus ICCIIO

been completed then the tapered plug or valve T is turned around by thehandle U through an eighth of a circle, which brings the ports T inconnection with the nozzles S and S and the port Tin connection with thenozzle S, at the same time closing the discharge-port T", while becauseof the port T being sufficiently long horizontally it still remains opento the port U in the pump barrel or cylinder A, in which position of thetapered plug U and its several ports in relation to the nozzles S, S, S,and S the pump is in readiness for being again filled with the liquidsbeing measured, mixed, blended, or diluted by making another upwardstroke of the piston or plunger B in the manner hereinbefore described.

When it is desired to measure, mix, blend, or dilute any two liquids inthe proportion of half of each, then a plug with ports therein arrangedin the manner shown in horizontal section at Fig. 9 is used. In thisFig. 9, the tapered plug T is shown in the position of its larger port Topen to the port U of the pump barrel or cylinder A and its port T opento the discharge port or nozzle U, or, in other words, in the positionwhich the ports in the plug T occupy with relation to the port U in thepump barrel or cylinder Aand the dischargenozzle U when the pump barrelor cylinder A is filled with mixed, blended, or diluted liquid and readyto be discharged. By turning the tapered plug T until its ports T becomeopen to the water-nozzles S" and S' then the ports Z Z in the tapered.plug T (shown at Fig. 9) simultaneously become open to the ports S S,through which'the vinegar, spirit, or other liquor to be diluted withwater is drawn simultaneously with the water through the ports T, whichopen to both the nozzles S" until the pump barrel or cylinder A isfilled with liquid mixed, blended, or diluted in the proportions of halfand half, and from which such liquid is discharged by turning the plug'1 back int-o the position shown at Fig. 9.

When it is desired to use the pump not as a mixing, blending, ordiluting apparatus, then the plug T is formed with but one port Ztherein, as shown at Fig. 8, when liquid passes into the port througheither of the nozzles S or S, as may be desired, and is dischargedthrough the discharge orifice or nozzle U by moving the plug '1circularly or upon its vertical axis until its port Z becomes shut tothe nozzle S and its other port Z becomes open to the discharge-port U.

It is to be understood that although I have on the annexed drawingsshown and in the preceding part of this specification have described mynew or improved mixing, blending, or diluting pump as having but fournozzles S S S S my improved pump may be provided with a greater or lessnumber of such nozzles than four and that the ports or openings in theplug or valve T are in all cases made to correspond with the number ofproportions wherein the liquids to be mixed, blended, or diluted, andthat my present invention consists within such modifications of what Ihave shown and described as is consistent with the claims hereinafterset forth.

Having now described the nature of my said invention and the bestsystem, mode, or manner I am at present acquainted with for carrying thesame into practical effect, I desire to observe in conclusion that whatI consider novel and original is 1. In a pump for measuring or mixingliquids, a pump-barrel provided with a seat for interchangeable plugs orvalves, admissionports in said plugs or valves, nozzles on thevalve-seat, one of the ports in each of the interchangeable plugs orvalves being always open to the pump-barrel, the other ports in theinterchangeable plugs or valves being open or closed to the desirednumber of nozzles of the plug or valve seat or casing, and which plugsor valves are moved by hand to close the discharge-port when thedrawingv stroke of the piston is being made, and to open thedischarge-port while closing the admission-ports when thedischarge-stroke oi. the piston is being made, all substantially ashereinhefore described.

2.
